4 Claims. (01. 128-305),

My invention relates to a surgical instrument used in the surgical operation known ascircumcision, which consists in removing a portion of the prepuce, thereby exposing the glans penis.

Heretofore, other circumcision instruments have been made in many different sizes, ranging from infant size where the glans diameter is approximately 1.1 cm. He") to adult size where the glans diameter is approximately 3.5 cm. (1%). The complete set of instruments represents a considerable investment for the average physician.

It is an object of my invention to provide a circumcision instrument having a removable cone and base plate whereby a kit of different sizes of cones and complementary base plates may be used with the one instrument.

Another object of my invention is to provide a circumcision instrument by means of which the entire operation may be performed without the aid of an assistant and in much less time than in any other existing method or instrument. Another object of my invention is to provide a, rapid means for tensioning the prepuce about the cone so that the surgeon may use his scalpel with certainty and accuracy.

Other objects of my invention are to provide an improved device of the character described, that is easily and economically produced, which is sturdy in construction, and which is highly efficient in operation.

With the above and related objects in view, my invention consists in the details of construction and combination of parts, as will be more fully understood from the following description, when read in conjunction with the accompanying drawing in which:

Fig. 1 is a plan view of a circumcision instrument embodying my invention.

Fig. 2 is a side view of the instrument illustrated in Fig. 1 showing in dotted lines how the cone holder may be shifted.

Fig. 3 is a bottom view of my circumcision instrument.

Fig. 4 is an end view taken al'ongftheline 4-4 of Fig. 1.

Fig. 6 is a fragmentary bottom view, in open position, of the base plate jaws.

Fig. 7 is a top view of the cone holder, the cone and base plate, the clamping nut having been removed.

Fig. 8 is a sectional view taken along the line 88 of Fig. 4.

Fig. 9 is a sectional view taken along the line 9-9 of Fig. 4. p

Referring now to the drawing, wherein similar reference characters designate similar parts, I show an instrument for performing circumcision safely and easily, and which reduces to a minimum the possibility of infection or hemorrhage. The circumcision is practically bloodless and in the very few cases where bleeding occurs, it is so slight that no suture nor even ligation is necessary.

The handle A of the instrument comprises two similar members It] and H, which members are joined together on a sliding pivot [4. The handle members also have projections 13 and I5, Whose laterally abutting surfaces are ridged, so that the handles may be locked at any degree of closure, in, the manner of a hemostat.

Pivoted to'the handle members [0 and I2; are a pair of complementary jaws l6 and 18, which are pivoted together at 2 0. The free ends 22, 24 of the jaws l6, I8 are semi-circular, and when abuttin one another, as in Fig. 3, they form an annular base plate, designated as B. Jaw 18 has a tit is which cooperates with a depression ll in jaw 16 to align the closure. The base plate B is inwardly hollowed on its lower surface, as at 26. A link C has one end fastened to the pivot 20, and has at its other end an elongated slot 28, within which the pivot i4 slides as the handle members are moved together or apart.

It can be seen that as the handles I0 and i2 I are moved together, the jaw ends 22 and 24 also outside of the stem of clamping screw 30.

move together, and vice versa.

Supported: pon link C is a bracket D, hinged to the link at 21. .The free end 29 of the bracket 1D is forked to admit the threaded end 32 of the Clamping; scr w 3.0.

The clampin screw 30 has an externally threaded end 32, an internally threaded end 34, and a shoulder 36 formed integrally with the screw at the base of the threaded end 32.

A penis-receiving cone or bell, designated generally as E, has a stem end 38 adapted to thread into the end .34 of the. clamping screw 3!), and has a cone portion 46. which is embraced by the semi-circular jaws of the base plate B, and the cone also has a cylindrical portion 42.

The hinged bracket D is. adapted to swing from its inoperative position, shown in phantom outline in Fig. 2, to its operative position, as shown in solid lines in the same figure. A thumb nut 44 operates upon the portion of the threaded end 32 which protrudes through the bracket D so that as the thumb nut is tightened, the cone is drawn into the annular base-plate D.

In order to stretch and grasp the prepuce to a position where it is held, I provide a tension carriage, generally designated as F, illustrated in Fig. 9 which is adapted to slide along the The tension carriage F consists of a plate 50 which l3, [5 of the handle for this purpose.

tioned at any point on theunthreaded length of the screw. The ends of the plate are bifurcated to receive a pair of clips 52 which are urged by coil springs 54 so that their arcuate ends 55 bear against the cylindrical portion of the cone E when the instrument is not in use but the clips stretch and grasp the prepuce when an operation is being performed. The arcuate ends 56 of the clips may be spread apart by compressing the finger ends 58.

In performing a circumcision, my instrument is used as follows:

With the patient upon the operating table, a cone E of the proper size for the glans penis (this may be determined by trial) is selected from the kit and assembled to the instrument. The thumb nut 44 is backed ofi, and the jaws of plate B are Spread apart. The cone is lubricated with Vaseline and slipped over the glans penis within the prepuce, so that the free end of the irenum is on a level with the rim of the cone. The prepuce is then grasped by the spring clips 52 and stretched by moving the carriage F back. The jaws l6, l8 of the plate B are then closed. and locked using the ridged projections The thumb screw 44 is turned until the cone portion 40 is drawn in firmly against the plate B.

At this point, the cone E completely covers the glans penis, and that portion of the prepuce which is to be removed is stretched about the cylindrical portion 42 of the cone on the upper side of plate B. The instrument is'leit in position for about 5 minutes, during which time the pressure of the cone against the plate produces 1 hemostasis or stoppage of the blood vessels in the annular region of the prepuce which is to be out. It is now a relatively simple matter for the surgeon to pass his scalpel around the cylindrical portion 42 of the cone E, close to the plate B, and remove the redundant tissue. The operation is now complete, and the instrument is released by backing off the thumb nut.

Since the cone E and the plate B are of one definite size, I provide in the kit a number of cones to cover the entire range of sizes previously described, together with the corresponding plates B. As shown in Fig. 8, the cones E are easily interchanged by screwing them into the end of clamping screw 30. Likewise, the jaws which form plate B are interchangeable, by removing the pivots at 21.

Although my invention has been described in considerable detail, such description is intended as being illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.

I claim as my invention:

1. A circumcision instrument comprising a pivotally mounted two-piece base portion wherein 4 i one end of said base portion forms a ring-like member, a penis-receiving bell adapted to pass through said ring-like member, means to adjustably clamp said bell in said ring-like member, and means mounted upon said first named means to stretch and to grasp the prepuce and to hold it in its proper position.
